Questions
How big is the Shield PCB?
It measures 53.3 × 54.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Shield use?
30 parts, built around the TPA2005D1DRB and LD39015M18R. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Shield KiCad files?
From the Agilack/eCow-logic repository on GitHub, at the commit this page was made from: the board is audio-shield-milky-sound/hw-audio-shield/shield.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Shield design in my own project?
Its repository states no licence, so its author keeps all rights: ask Agilack before reusing the design.
